CVE-2026-34635 is a use of hard-coded cryptographic key vulnerability in Adobe ColdFusion. The flaw stems from insecure key management in which a cryptographic key is embedded in the product, weakening the protection provided by security controls that rely on that key. Successful exploitation can allow a low-privileged attacker to bypass security features and obtain unauthorized read and write access without requiring user interaction. The vulnerability affects ColdFusion 2025.0.11 and earlier and ColdFusion 2023.0.22 and earlier. The issue is associated with changed scope, indicating compromise can extend beyond the originally authorized security boundary.
